We recently investigated a typical case of a patient who suffered from achromatopsin. The patient was a right-handed, 73-year-old man with atrial fibrillation who suddenly lost his color vision while watching television. He has subsequently complained that “everything looks only black and white”. Both color naming and color pointing were severely disturbed, while the concept of color was completely preserved. Ordering according to brightness was also well maintained. There was no additional neuropsychological disturbance such as aphaisa, alexia or prosopagnosia. The patient with cerebral achromatopsia can thus discriminate colors according to a scaled “brightness-darkness axis”. Brain MRI revealed ischemic changes located in the bilateral occipital lobes associated with laminal cortical necrosis of the fusiform gyrus. These findings suggest that the cerebral achromatopsia demonstrated in the present patient is due to a partial defect of color perception caused by bilateral occipital lobe lesions.
